Howdy Liz,
Welcome to the 100 club! Don't worry about those gym prancers, they aren't worried about you!!
If you are part of WW, then you know that you don't have 100 to lose. You have 10% to go! I had a lot of mental baggage to get over when looking at the total picture. Breaking it down into small pieces is much simpler. Figure by the 5th 10%, I'll make goal!
WW is a great program and these are great folks here. Just find a thread and dive in!
All the best!
